This'is effected bycon necting the top comb: arm to'an arm or lever keyed upon a separateshaftth top. comb shaft-with means for oscillating or rocking thelatter. The-nipper shaft and the top comb shaft rock exactly in time asthey should, but it is not necessary that they should have the sameamplitude or extent ofmovement; it is indeeddesirable that the amplitudeor extent of throw of the top comb should be capable of variation tosuit different types of fibres being dealt with. It is an object of thepresentinvention to provide simple means whereby this variation can beeffected 7wlinflsiiedi'whilst'ipreserving the synchronismof'movementflfo'f. the'nipperi and top comb and 4 Claims. 11. 19-116)without altering the working position of the latwhich is pivoted, theotherend adjustably engaging upon a part associated with the top combshaft or the rocking means therefor, asthe case may be. Mostconveniently the means for ad- 7 justable engagement consists of anarcuate slot in which engages a, pin borne by the adjusting rod.Adjustment of the pin in the slot, with movement of the adjusting rodaround its pivotal point which constitutes the centre of the arc, thusserves to vary the amplitude or extent of throw of the top combs byvarying the extent of oscillation of the top comb shaft; without inanyway affecting the working position of a top comb.

In Nasmith combing machines, two types are in industrial use, which maybe differentiated broadly by stating that in one form the swingingmachine nipper hinges upon a point below the combing machine cylinder;whilst in the other the nipper hinge point is above the said cylinder.'This present invention is illustrated'in the accompanying drawings withconvenient mechanical arrangements by way of example as applied to eachof these types of machine. In these drawings Figur l is a side elevationof mechanism as applied to the first mentioned type of Nasmith combingmachine; Figure 2 is a similar View of mechanism dc 'gned forapplication to i-thesecond named-atypeeand Figure 3. i1lustrates amodified form of; device of Figure 2.

Whentheparts arein the position shown inthe figure the top comb, operated from the top comb shaft T, is in its,most forwardposition, and it will be obvious that the pin I2 can beadjusted in the-slot in any position without. in any way afiectingtheposition-of the top comb itself. Anyincrease or diminution .of theamplitude of swing of the top comb is effected at the rear end of itsmovement where the comb is inoperative, but this increase or diminutionof the amplitudeof swing has a a slight effect upon the distance the topcomb travels during its operative or detaching period, which is theresult desired. The rod l l is provided with; adjusting nuts l3 so thatthe shaft T and all the appended parts of the top comb can be adjustedsimultaneously.

As will be understood, the mechanism described and illustrated isduplicated at the other side of the machine.

In Figure 2 of the drawings the parts shown for the carrying out of thisinvention are as those described with reference to Figure 1, theassembly being however varied to suit the type of combing machine inwhich they are employed. In this Figure 2 the top comb carrier is shownat I4; and the top comb shaft at T. The three-armed lever I5 is rockedabout the pivot I6 as usual, and has pivoted upon its upper arm at IIthe end of link 18 the other end of which is pivoted upon the pin orstud 19 which engages as shown the arcuate slot 20 formed in lever 2|,to be adjusted 7 shown in'Figure 1, that the drive may be adjustedact-=21 is struck from:theLpivotaI pOint u'pon ever sesame coPY aboutpivot point I! as centre, and from which centre the arc of slot 20 isstruck.
